Winix 5510 Air Purifier Review: Is it the New King?

Full Review

Over the past few years, Winix has updated its lineup of air purifiers, introducing several new models.

For me, one of the most interesting is the Winix 5510, which, according to Winix, is the successor to one of its most popular models, the Winix 5500-2.

We tested its performance, noise levels, and power consumption, and in this review, I’ll analyze it in detail and compare it with other competing models.

The Winix 5510 comes with several advanced and smart features, and below, you’ll find out just how important they are and whether this model is a true improvement over its predecessor.

How We Tested the Winix 5510?

1. For the filter efficiency testing, we used the Temtop LKC-1000S laser particle meter, which measures PM2.5 (µg/m3), PM10 (µg/m3), Particles (per/L), and HCHO (mg/m3) in the air, and also calculates the AQI.

2. We placed the Winix 5510 in a 320 sq. ft. (30 m²) room. Then, we recorded the initial air quality values using the Temtop laser particle meter and let the Winix 5510 run at maximum speed.

3. After 60 minutes, we measured the new values using the Temtop laser particle meter and saved the data.

4. Next, we placed the Winix 5510 in a glass box, which we then filled with smoke. Then, we measured how much time was needed for the air purifier to remove all the smoke from the box.

5. Using a special noise measurement tool, we tested the air purifier’s noise level at all speeds. We measured the noise level on the dBA scale.

6. Finally, we measured the power usage at all speeds using an energy meter, after which we calculated how much it would cost to use the device at a particular fan speed for one month. For reference, we used an energy price of $0.12 per kWh.

Winix didn’t disappoint in performance tests—on the contrary, it proved its reputation and remained one of the best air purifiers we’ve tested so far.

The Winix 5510 has a CADR of 253 CFM (430 m³/h), making it ideal for rooms up to 392 sq. ft. (36 m²). At this size, it can completely clean the air 4.8 times per hour.

To evaluate its efficiency, we tested the Winix 5510 in two rooms of different sizes, while we measuring how well it captures small airborne particles.

Additionally, I used this model in my home for a short period to evaluate its real-world performance. I found that it isn’t only extremely effective at capturing airborne particles but also effortlessly neutralizes light household odors.

Testing in a 320 sq. ft. (30 m²) Room

In the first test, we placed the Winix 5510 in a 320 sq. ft. (30 m²) room and let it run at maximum speed for 60 minutes.

During this time, it successfully reduced PM2.5 particulate matter from 104.9 to just 4.7 µg/m³.

This resulted in an impressive 96% improvement in air quality, placing the Winix 5510 among the best air purifiers we’ve tested.

It achieved the same outstanding result in this test as the powerful Coway AP-1512HH and Levoit Vital 200S.

Overall, I’m extremely satisfied with the Winix 5510 performance in this airborne particle removal test.

The Winix 5510 has five fan speeds, and we measured noise levels separately at each speed using a specialized noise measurement tool.

At the lowest speed, it produces 40.2 dBA, which is quite impressive and within the range of some of the quietest air purifiers we’ve tested. For comparison, the Alen FLEX produces 41.2 dBA at its lowest speed.

However, at maximum speed, the Winix 5510 is noticeably louder, producing 65.7 dBA. As shown in the provided chart, while it is better optimized than the Winix 5500-2 at maximum speed, it remains significantly louder than some competing air purifiers in its class.

Considering its high CADR and low noise levels at low speeds, I would say the Winix 5510 is well-optimized overall and not too loud.

Although I believe Winix could further optimize the motor in the newest Winix 5510 model, I can’t say I’m disappointed with the CADR performance delivered by its 65W motor.

At maximum speed, this air purifier consumes approximately 53.4W. If used at this speed 24 hours a day for a month, your electricity bill would increase by about $4.68.

Compared to other similar air purifiers in its class, it ranks fairly well. For example, the Blueair 211+ would cost around $4.29 under the same conditions, while the Levoit Core 400S would cost just $3.07.

Besides electricity costs, there’s also the cost of replacement filters. The Winix 5510 uses long-lasting filters that last up to 12 months.

However, since it is a newer model, the availability of third-party replacement filters is still limited, which isn’t the case with the Winix 5500-2.

Additionally, the replacement filter is slightly more expensive than I expected. But, if we assume that Winix won’t increase the filter price and consider its well-optimized motor, I would say that the Winix 5510 is relatively affordable to maintain annually.

Filtration Technology

The Winix 5510 uses the Filter Q, a newly designed filter that is compatible only with the 5510 and 5520 models.

This air purifier features a four-stage filtration system, which includes a pre-filter, activated carbon filter, True HEPA filter, and PlasmaWave technology.

The True HEPA and activated carbon filters are rectangular and positioned at the front, with the pre-filter attached just before the activated carbon filter.

While I truly like the quality of the True HEPA and activated carbon filters, I would be even more satisfied if they were larger, ideally at least as big as the ones used in the Winix 5500-2 (Filter H).

Pre-filter

The washable nylon mesh pre-filter serves as the first stage of filtration. It looks like a mosquito mesh.

This filter effectively traps large particles such as dust, hair, pet hair, and similar.

Apart from capturing large particles and enhancing overall filtration efficiency, its main purpose is to extend the lifespan of the other filters, particularly the True HEPA filter.

The easy-to-clean, washable pre-filter makes the Winix 5510 an excellent choice for pet owners.

Activated Carbon Filter

The second stage of filtration is a pellet-based activated carbon filter, which isn’t washable.

This filter effectively neutralizes odors, including pet smells, cooking odors, cigarette smoke, VOCs, and other household pollutants.

It is significantly more efficient than a standard carbon-coated filter, which is why the Winix 5510 delivered great results in our odor neutralization tests, particularly in the smoke removal test.

True HEPA Filter

The True HEPA filter is the most crucial stage of this air purifier. As the third stage of filtration, its primary function is to capture small airborne particles.

It effectively traps dust, pollen, allergens, smoke, mold spores, and other similar pollutants.

I strongly believe that this filter is the key factor behind the outstanding performance of this air purifier in our tests.

PlasmaWave

The final stage of filtration is PlasmaWave technology, which is enabled by default but can be turned off if desired.

This technology works by applying a safe electrical discharge to create both positive and negative ions from moisture in the air. These ions attach to airborne pollutants such as viruses, bacteria, odors, and volatile organic compounds (VOCs), and remove hydrogen from their molecular structure, effectively neutralizing them into harmless substances like water and carbon dioxide.

It’s important to note that the Winix 5510 is CARB and Energy Star certified, meaning it meets strict safety standards. Testing has confirmed that it either doesn’t produce ozone at all or remains well below the allowed limits, ensuring it is completely safe to use.

How to Replace the Winix 5510 Filters?

Since the pre-filter is the only washable filter on the Winix 5510, the other filters will need to be replaced periodically.

The Winix 5510 features a filter reset indicator, which notifies you when it’s time to replace the filter. Additionally, you can check the filter status directly through the smart app. The filters have a lifespan of up to 12 months.

The filter replacement process is simple and requires just a few easy steps.

Setup and Installation

This air purifier doesn’t require any advanced setup before its first use. All you need to do is prepare the filters and remove the protective plastic from the device.

To prepare the filters, open the front cover, remove the filters, unpack them from the plastic bag, and then reinsert them into the device.

Your Winix 5510 is now ready to use. Place it in a suitable location, but please be sure that airflow isn’t blocked. Plug it in, and turn it on.

Design

This is one of the few Winix air purifiers that boast a modern, stylish design that is perfectly aligned with trends.

I really like that Winix focused on aesthetics, at least with this model.

In comparison with its predecessor, the Winix 5500-2, the Winix 5510 is significantly more attractive, modern, and elegant than its predecessor.

The build quality is outstanding, with high-quality plastic and a charcoal gray finish.

At the front, there is a detachable panel with has oppenings for drawing air in. Below the control panel are filters.

It has a slot at the top back of the device, which is useful if moving the device from room to room often.

I believe this Winix model will fit easily into almost any environment.

Controls and LED Indicators

At the top of the Winix 5510, you’ll find a control panel with touch buttons and LED indicators.

The panel includes buttons for power, fan speed, WiFi, PlasmaWave, and filter reset. Each button lights when activated, and above some of them, there are indicators that represent the current state.

Additionally, there is a dedicated LED light on the front panel that changes color based on the current air quality in the room, providing real-time feedback.

Airflow

The Winix 5510 has air inlets located on the front panel, sides, and under the front panel.

The air passes through all filtration stages before exiting through the grilles on top.

Size and Dimensions

What I truly like is that Winix has reduced the size of the Winix 5510 air purifier.

It’s now more compact while delivering a higher CADR than its predecessors.

The Winix 5510 measures 13.6 × 8.3 × 22.2 inches (34.6 × 21.1 × 56.4 cm) and weighs 13.3 lb (6 kg).

What’s in the box?

When you buy the Winix 5510, you will get a 1x air purifier, pre-installed filters, and a user manual.

Features Overview

What sets the Winix 5510 apart from the Winix 5500-2 is its addition of smart features.

This model is compatible with the Winix Smart App and includes several advanced features that are accessible through the app.

Air Quality Sensor & Indicator

The air quality sensor is located on the front, just below the air quality LED indicator.

This sensor detects odors in real time, but doesn’t measure PM2.5 particulate matter, unlike some similar air purifiers.

It continuously monitors air quality and sends real-time data to the smart app, air quality indicator, and auto mode.

The air quality indicator, a small front-facing LED light, changes color based on the current air quality. Refer to the table below for a breakdown of what each color represents.

LED Light Color	Air Quality
Blue	Good
Orange	Fair
Red	Poor

If you switch to sleep mode, the LED indicator will turn off.

Auto Mode

Auto mode is another feature that works in combination with the air quality sensor.

When enabled, the Winix 5510 continuously monitors air quality and automatically adjusts the fan speed based on detected pollution levels.

This is a useful feature, but its functionality is somewhat limited by the sensor’s ability to detect only odors.

For example, since this sensor doesn’t detect pollen, the air purifier will remain at the lowest speed when in auto mode, even if pollen levels are high. However, if placed in the kitchen, it will immediately detect cooking odors and adjust the fan speed accordingly.

Sleep Mode

When sleep mode is activated, the Winix 5510 reduces the fan speed to its lowest setting, which is even lower than the first speed.

Additionally, the LED air quality indicator is disabled in sleep mode.

It’s important to note that PlasmaWave automatically turns off when sleep mode is active, but you have the option to turn it back on if desired.

Based on our tests, the Winix 5510 produces just 40.2 dBA in sleep mode, and since it dims all light indicators, I believe it’s an excellent choice for bedrooms.

Light Sensor

This is a feature I don’t particularly like in practice, and I wish there were an option to disable it.

It’s a simple sensor that detects ambient light, and if the room is dark, it automatically switches the air purifier to sleep mode.

Warranty

The Winix 5510 initially comes with a one-year warranty. However, Winix offers an option to extend it for an additional year.

To do so, simply register your device on the Winix website—it’s that easy!

The process takes just a few simple steps and extends your warranty to two years. So, don’t wait—register your device immediately after purchase!

Winix Smart App

To be honest, this was my first time using the Winix Smart App. In fact, the Winix 5510 is the first smart air purifier from this brand that I’ve tested.

However, I’ve tried dozens of other smart air purifier apps, and I must say that the Winix Smart App lags slightly behind more advanced options like VeSync or Blueair’s smart app. For instance, the VeSync app provides a much more detailed overview of air quality data and scheduling features.

The Winix Smart App is relatively simple. It allows users to control the air purifier remotely, view detailed air quality data, check filter wear, and set basic schedules.

One feature I find lacking is advanced scheduling, as seen in Levoit’s smart air purifiers. Additionally, I would like the ability to check real-time air quality data even when the purifier is turned off.

The device setup and app connection process is simple and hassle-free. Many premium air purifier brands, such as the Molekule Air, struggle with connectivity issues, but that’s not the case with Winix.

Despite a few drawbacks, I believe the Winix Smart App significantly enhances the usability of the Winix 5510, especially when compared to non-smart air purifiers.

The smart app is available for Android and iOS devices.
